“Becoming pretty doesn't just change the way you look," she said. "No," David said. "It changes the way you think.”

“I can pick up the city feeds on my antenna. It said they were going to change you all. Turn you into something less dangerous. Are you still...?"She gazed at him. "What do you think, David?"He peered into her eyes for a long moment, then sighed and shook his head. "You just look like Tally to me."She looked down, her vision blurring.What's the matter?"Nothing, David." She shook her head. "You just took on five million years of evolution again."I what? Did I say something wrong?"No." She smiled. "You said something right.”

“She looked at David closely, and the feeling was still there. She could see that his forehead was too high, that a small scar cut a white stroke through his eyebrow. And his smile was pretty crooked, really. But it was as if something had changed inside Tally's head, something that had turned his face pretty to her.”

“It's not the way Zane looks, David," she said, her voice trembling with anger. "It's because he makes me bubbly, and because we took a lot of risks together. It could just as easily be me lying there, and he would stay with me if it was.""It's just programming!" "No. It's because I love him.”

“You all say you need us. Well, maybe you do, but not to help, with the millions of bubbly new minds about to be unleashed, with all the cities coming awake at last. Together, you're more than enough to change the world without us. So from now on, David and I are here to stand in your way. You see, freedom has a way of destroying things.”

“You and David could both be right. Maybe human beings are programmed … to help one another, even to fall in love. But just because it's human nature doesn't make it bad, Tally. Besides, we had a whole city of pretties to choose from, and we chose each other."-Zane”

“You look beautiful - David”
